hello I just saw a bug when you climb high into the air to the 500, 600 meter game does not respond this has not very serious but must be corrected if the bug there when you walk near a Rebora as the character is sucked into the holes or the bug is not thick enough layer passes through this and very .... Finally otherwise good game long life and it will be popular as jespers Minecraft etc. .... ^ ^

The height bug has already been brought to Aaron's attention I believe, and I'm sure he's already working on a solution. Possibly a building height limit?

The thin layers causing you to pass through is sloppy collision detection and Aaron has already said he is going to improve upon it. Collision detection isn't exactly the easiest thing to work on, though. Give him some time xD
